Description of Magnesium Aluminum Spinel:
Magnesium Aluminum Spinel is produced by mixing the industrial alumina with the high-purity caustic-burned magnesia, smelting with high temperature more than 2000 degree centigrade in the electric-arc furnaces. And it can be processed into various sizes of particles according to the clients’ demands. Its grain is well developed with the features of compact texture and uniform structure, and there fore is the high-grade raw material for producing refractory products with high in density and good thermal shock resistance ( spinel and magnesia, etc. ).
Magnesium Aluminum Spinelhas the characteristics of high bulk density, high thermal shock resistance, strong corrosion resistance and slag- resistance. It is widely used in iron and steel melting, cement rotary kiln and glass furnace, as the ideal material for manufacturing cast sliding plate, nozzle bricks, ladle bricks and open hearth furnace bricks, as well as the basic material for ecotone bricksof large cement kilns, medium cement kilns, refractory castable materials, and first-class and medium-class kiln furniture.
Application of Magnesium Aluminum Spinel:
As the important raw material for manufacturing refractory products and fine ceramics,
widely used in refractory material products as for making the steel furnace roofs,
converters and ladles, the ecotone bricks of large rotary cement kiln,
and the glass furnace regenerators, etc.
